FERDINAND LINDNER, OF DAYTON, OHIO.

IMPROVEMENT IN APPARATUSFOR MAKING BUTTON-HOLES.

Specification forming part of Letters Patent No. 58,651, dated October 9, 1866.

To all whom fit may concern:

Be it known that I, FERDINAND LINDNER, of the city of Dayton, in the county ot Montgomery, in the State of Ohio, have invented a new and Improved Button-Hole Regulator 5 and I do hereby declare that the following is an exact description thereof, reference being had to the accompanying drawings, making a part of this specication, in whieh Figure l is a top view ot' the button-hole regulator. Fig. 2 is a side view of the same. Fig. 3 is an under-side or bottom view of the same. Fig. 4 is a section ot' line AB. Fig. 5 is a section ot` line C D.

Similar letters ot reference indicate corre spending parts in the several figures.

The object of this invention is to secure and lirnily hold the cloth or any other fabric between the jaws of an instrument constructed out of steel or any other material while a button-hole is being worked, preventing the cloth or fabric from slipping, and also from being soiled between the thumb and finger of the workman, and also to regulate the needle and guide the thread, making the seam perfectly straight on the inner and outer side ot' the fabric.

To enable others skilled in the art to understand myinvention, I will describe its construe tion and operation.

Fig. 2 represents a side view of the buttonhole regulator with the jaws open. The upperjaw, A, is round on top and concave on the under side, as seen at a., and is a continuation ofthe bow-spring I-I. The under jaw, B, is self-adjustable, rounded on top, as seen at Z1,

so as to lit into the concave a in upperjaw, A. The object of this is to prevent the fabric from slipping, as it would be'inore likely to do it' the inner surface of the jaws were flat.

The under jaw, B, is composed ot' steel and connected with the bow-sprin g H by means of the hinge orjoint J, by which it adjusts itselt' to the thickness of the fabric, causing the pressure to be equal the entire length of the button-hole.

The jaws A and B are opened by means of the levers D D, secured to the plates E by the pins d d. By pressing the handles or thumbpieces G G the levers D D are forced out against the inside of the bow-spring II at k L, causing the jaws to Opern-as seen in Fig. 2.

The small seinicircular plates F are placed inside the bow-spring H, for the purpose of securing the levers D D and forming a fuleru 1n upon which the levers D D act when the pressnre is on the handles G G. The orifice L in the bow-spring II is for the levers to pass through. I

Havin g described my invention, what I claim as new, and desire to secure by Letters Patent, is-

A button-hole regulator made of steel or any other suitable material, having the jaws A B, bow-spring H, levers D D, and handles G G, as herein described, and for the purposes set forth.

FERDINAND LINDNER.
